Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and in particular relates to a fixed structure for machining the front axle of a tractor. Background Technology

[0002] A tractor is a self-propelled power unit used to traction and drive work machinery to complete various mobile tasks. It can also be used as a stationary power source. It consists of an engine, transmission, running gear, steering, hydraulic suspension, power output, electrical instruments, driving controls, and traction systems or devices. Engine power is transmitted to the drive wheels through the transmission system, enabling the tractor to move. In real life, rubber belts are commonly used as the power transmission medium. Tractors are classified by function and purpose into agricultural, industrial, and special-purpose tractors; and by structural type into wheeled, tracked, boat-shaped tractors, and self-propelled chassis tractors. The tractor front axle is a mechanical component connected to the front of the tractor, used to drive the front wheels. It is responsible for bearing the load at the front of the tractor and transmitting engine power to the front wheels, thus propelling the tractor forward. The front axle is usually made of various metal materials, such as steel alloys. These materials need to be processed through cutting, welding, drilling, and other processes to form the specific shape and structure of the front axle. A fixed tractor front axle ensures the stability of the front axle's position during processing, guaranteeing machining accuracy.

[0003] Currently, during the processing of tractor front axles, in order to improve the processing effect, it is necessary to fix them. However, the existing fixing devices generally use a double-threaded rod to control the clamping plate to fix the tractor front axle. The vibration generated during processing can easily cause the double-threaded rod to loosen, making it impossible to clamp and fix properly, thus affecting the processing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing structure for machining the front axle of a tractor. By setting a ratchet and a pawl to lock the bidirectional threaded rod, it solves the problem that existing fixing devices generally use a bidirectional threaded rod to control the clamping plate to fix the front axle of the tractor. The vibration generated during machining can easily cause the bidirectional threaded rod to loosen, making it difficult to clamp and fix properly, thus affecting the machining process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fixed structure for processing the front axle of a tractor, including a workbench and two chassis, and a support mechanism and a clamping mechanism are provided on the workbench.

[0007] The support mechanism includes a bidirectional threaded rod rotatably connected to the inner wall of the worktable, one end of which extends rotatably to the outside of the worktable. A rocker arm is fixedly connected to the outer wall of the bidirectional threaded rod, and a ratchet is fixedly connected to the outer wall of the bidirectional threaded rod. A protective shell is fixedly connected to the right side of the worktable, and a rotating rod is fixedly connected to the inner wall of the protective shell. A rocker arm is rotatably connected to the outer wall of the rotating rod, and a pawl is fixedly connected to the outer wall of the rocker arm. The pawl contacts the ratchet. A fixing block is fixedly connected to the right side of the worktable, and a spring is fixedly connected to the top surface of the fixing block. The end of the spring away from the fixing block is fixedly connected to the pawl. Two internal threaded blocks are threadedly connected to the outer wall of the bidirectional threaded rod, and two sliders are fixedly connected to the top surface of each of the two internal threaded blocks. Four sliding grooves are formed in the inner top wall of the worktable, and the inner walls of the four sliding grooves are slidably connected to the four sliders.

[0008] Furthermore, a support plate is fixedly connected to the top surface of each of the two internal threaded blocks, and two guide grooves are opened on the top surface of the workbench. The inner walls of the two guide grooves are slidably connected to the sides of the two support plates respectively.

[0009] Furthermore, each of the two support plates has two threaded posts fixedly connected to its top surface, and each of the four threaded posts is threaded with a nut. Each of the two support plates has a pressure plate on its top surface, and the two pressure plates are respectively rotatably penetrated by the four threaded posts in pairs.

[0010] Furthermore, the clamping mechanism includes an adjustment box fixedly connected to the top surface of the workbench. A bidirectional threaded rod is rotatably connected to the inner wall of the adjustment box. One end of the bidirectional threaded rod rotatably passes through the adjustment box to the outside. A rocker arm is fixedly connected to the end of the bidirectional threaded rod away from the adjustment box. Two internal threaded blocks are threadedly connected to the outer wall of the bidirectional threaded rod.

[0011] Furthermore, two sliders are fixedly connected to the top surfaces of the two internally threaded blocks, and four sliding grooves are provided on the inner top wall of the adjusting box. The inner walls of the four sliding grooves are slidably connected to the four sliders, and connecting posts are fixedly connected to the top surfaces of the two internally threaded blocks. Two guide grooves are provided on the top surface of the adjusting box, and the inner walls of the two guide grooves are slidably connected to the two connecting posts.

[0012] Furthermore, clamps are fixedly connected to the sides of the two connecting columns that are close to each other, and rubber pads are fixedly connected to the sides of the two clamps that are close to each other.

[0013] Furthermore, electric push rods are fixedly connected to the top surfaces of both chassis, and the bottom surface of the worktable is fixedly connected to the output ends of the two electric push rods. Two slide rods are fixedly connected to the top surfaces of both chassis, and four sliding grooves are provided on the bottom surface of the worktable. The four slide rods are slidably connected to the inner walls of the four sliding grooves.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a support mechanism, rotating the rocker arm separates the pawl from the ratchet. Then, rotating the rocker arm drives the double-threaded rod to rotate, which in turn moves the internal threaded block on the double-threaded rod along the guide groove, bringing the support plate to the designated position. Then, the spring's return locks the ratchet and pawl on the double-threaded rod, fixing the position of the support mechanism and preventing displacement. The tractor front axle is then placed on the device and fixed with a pressure plate and nut. The above-mentioned support mechanism not only fixes the tractor front axle but also prevents vibrations during processing from loosening the fixing device, allowing processing to proceed smoothly.

[0016] 2. By incorporating a clamping mechanism, rotating the rocker arm separates the pawl from the ratchet. Rotating the rocker arm drives the double-threaded rod to rotate, causing the internal threaded block on the double-threaded rod to move along the guide groove. This, in turn, moves the clamping plate on the connecting column to compress the tractor's front axle. The spring's return locks the ratchet and pawl on the double-threaded rod, fixing the clamping mechanism in place. Rubber pads further stabilize the tractor's front axle. Electric push rods and slide rods allow the device to adjust the processing height. This device not only secures the tractor's front axle but also prevents it from shifting due to processing forces. Furthermore, it allows for quick adjustment of the processing height, saving time and significantly improving processing efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Please see Figure 1-5 As shown, this utility model is a fixed structure for processing the front axle of a tractor, including a workbench 1 and two chassis 4. The workbench 1 is provided with a support mechanism 2 and a clamping mechanism 3.

The inner walls of the four sliding grooves 293 are slidably connected to four sliders 292 respectively. A support mechanism 2 is provided. By rotating the rocker arm 25, the pawl 26 is separated from the ratchet 23. Then, by rotating the rocker arm 22, the double-threaded rod 21 is rotated, which in turn drives the internal thread block 291 on the double-threaded rod 21 to move along the guide groove 294 and make the support plate 295 reach the designated position. Then, the spring 28 rebounds and locks the ratchet 23 on the double-threaded rod 21 with the pawl 26, fixing the position of the support mechanism 2 and preventing displacement. Then, the tractor front axle is placed on the device and fixed by the pressure plate 297 and nut 298. The support mechanism 2 not only fixes the tractor front axle, but also prevents the fixing device from loosening due to vibration generated during processing, so that processing can proceed smoothly.

[0029] Support plates 295 are fixedly connected to the top surfaces of two internal threaded blocks 291. Two guide grooves 294 are formed on the top surface of the worktable 1.

A rocker arm 33 is fixedly connected to the end of the threaded rod 32 away from the regulating box 31. Two internally threaded blocks 34 are threadedly connected to the outer wall of the threaded rod 32. Two sliders 35 are fixedly connected to the top surface of each of the two internally threaded blocks 34. Four sliding grooves 36 are formed on the inner top wall of the regulating box 31.

The top surfaces of the two bases 4 are fixedly connected to two sliding rods 42. The bottom surface of the worktable 1 has four sliding grooves 43. The four sliding rods 42 are slidably connected to the inner walls of the four sliding grooves 43. A clamping mechanism 3 is provided. By rotating the rocker arm 25, the pawl 26 is separated from the ratchet 23. By rotating the rocker arm 33, the bidirectional threaded rod 32 is rotated, thus rotating the bidirectional threaded rod 32. The internal threaded block 34 on the tractor moves along the guide groove 37, which in turn moves the clamping plate 39 on the connecting column 38 to press against the tractor front axle. Then, the spring 28 rebounds and locks the ratchet 23 and pawl 26 on the double threaded rod 32, fixing the position of the clamping mechanism 3. The rubber pad 391 makes the tractor front axle more stable. The electric push rod 41 and slide rod 42 allow the device to adjust the height required during processing. The above-mentioned device not only fixes the tractor front axle but also prevents it from shifting due to the force generated during processing. It also allows for quick adjustment of the processing height, saving time and greatly improving processing efficiency.

[0030] A specific application of this embodiment is as follows: By setting up a support mechanism 2, rotating the rocker arm 25 separates the pawl 26 from the ratchet 23. Then, by rotating the rocker arm 22, the bidirectional threaded rod 21 is rotated, which in turn moves the internal thread block 291 on the bidirectional threaded rod 21 along the guide groove 294, and the support plate 295 reaches the designated position. Then, the spring 28 rebounds and locks the ratchet 23 and pawl 26 on the bidirectional threaded rod 21, fixing the position of the support mechanism 2 and preventing displacement. Then, the tractor front axle is placed on the device and fixed by the pressure plate 297 and nut 298. The support mechanism 2 described above can not only fix the tractor front axle, but also prevent the fixing device from loosening due to vibration generated during processing, so that processing can proceed smoothly.

[0031] By incorporating a clamping mechanism 3, rotating the rocker arm 25 separates the pawl 26 from the ratchet 23. Rotating the rocker arm 33 drives the bidirectional threaded rod 32 to rotate, causing the internal thread block 34 on the bidirectional threaded rod 32 to move along the guide groove 37. This, in turn, moves the clamping plate 39 on the connecting column 38 to press against the tractor's front axle. The spring 28 then locks the ratchet 23 and pawl 26 on the bidirectional threaded rod 32, fixing the position of the clamping mechanism 3. The rubber pad 391 further stabilizes the tractor's front axle. The electric push rod 41 and slide rod 42 allow the device to adjust the required height during processing. This device not only fixes the tractor's front axle but also prevents it from shifting due to forces generated during processing. Furthermore, it allows for quick adjustment of the processing height, saving time and significantly improving processing efficiency.
